To all whom iv may, coficerm. Be it known that I, EDWARD S. HYDE, a citizen of the United States, residing at Dubuque,

in the county of Dubuque andState of Iowa,

have invented certainnew and useful-Improvements in a Combined Flush-Tank and Man-hole; and I do hereby declare the following to be a-full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to theconstruction and care of sewers and consists generally in combining a manhole with a flushing tank, whereby obstructions maybe more easily removed from the flushing apparatus and the sewer pipes.

In the construction and care of sewers,especially those of small diameters, it becomes necessary to construct, at short intervals, what are called manholes into which those having the care of the sewer can enter and inside of the tank with the tank near the top, in

order that there may be a perfect communication of airwith the flushin g apparatus, which is generally siphonic and also that the warm air of the sewer may keep the tank from freezing. Again, whenever the flushing apparatus now in use, becomes obstructed, from any cause, before the one having charge of the sewer, can enter the tank to remove the obstruction or repair the same, the water must be first bailed out or removed in some way and if the sewer becomes obstructed between the Hush tank and the next nearest manhole, it is necessary under the present system of sewers, to clean them from the manhole back up to the flush tank, from the fact there is no opening from the tank into the sewer pipe except through the flushing apparatus and this is not of sufficient size to introduce the scraper with which to cleanthe sewer down to the manhole.

The object of my invention is to avoid these various defects in the present modes of caring for sewers and to so combine the manhole with the flush tank that one can enter the tank and remove any obstruction without removing the water used in fiushing or he can mechanicallyflushthe sewer if the flushing apparatus for any cause will not work and while hole, or otherwise to clean the sewer pipes, the same as between two manholes. I also do away with the additional pipe from the sewer to the top of the siphon for supplying air to operate the siphon and to protect the tank from freezing, all of which will be more fully hereinafter described and claimed.

For the better understanding of my invention, attention is invited to the accompanying drawings in which Figure 1, is a section of my tank and manhole combined. Fig. 2, is a plan view of the same.

Like letters denote corresponding parts in both of the figures.

A little to one side of the middle of the tank A, I construct a water tight partitionF, extending up about two-thirds of the height of the tank, dividing the lower part of the tank A, into two parts or spaces T, and M. Through the lower middle of this partition F, I cut the hole I, about four or five inches in diameter and insert in it a water tight plug I. The object of. this is to draw off the water from the flushing part of the tank, Whenever it is necessary either to repair the flush tank or to mechanically clear out the sewer pipe by flushing it. Under the partition F, I also insert the end D, of the sewer pipe E,and connect it with the basin 0, of the flushing apparatus to carry the water from the flushing apparatus into the sewer E.

I supply the space T, with the fiushingapparatus a, and the basin 0, and the faucet B, for supplying water to the flushing apparatus. It will be seen that all of the furniture of the space T, may be of any well knownconstruction. I have shown the siphonic system, as

being the one most usually employed in this vicinity.

Along the floor of the space N, runs the sewer pipe E, which is open along its upper in the'tank can help operate the scraper between the tank and the next nearest mansurface its entire length in, thespace M, as:

shown atJ. The object of this construction will presently appear. g

The manner of operating my device is as follows: Whenever the flushin g apparatus becomes obstructed or the sewer needs cleaning,

the one having the care of the sewer, enters the man-hole, without first having to bail out the water in the flush tank space '1, and,

stand in the space M. New standing in the space M, he can reach over the partition wall F, and remove any obstruction, which isabove or around the upper part of the flushing ap paratus a; but if the obstruction be below, in

and around the basin 0, then hetcan pass his hand through the-pipe D,'and removeit; If

he desires to remove the'water from the space T, to flush the sewer or to cleanthetank" T,; he pulls-onttheplng I in thehole I, and allows thewater to escape rapidly intothe sewer E,

through the open part J. r This will flush the sewer pipe the same asathe flushing apparel-r tus. Again if the sewer pipe beconles obstructedhe can pass a float; to whichisattached a scraper down throughthe sewer E, to the party in the next nearest man-hole and the two canoperate the scraper the same as between any two adjacentlnan-holes and s It will be seen that aman-hole constructed 1 claim, and desire to secure by Letters Pat ati thus clean out the sewer. The air to operate the siphon andtoprevent freezing will escape into the tank through theopening J, in the, sewer pipe E, and thus dispense with the extra pipe now in use inmost flush tanks.

in this manner and containinga flushing apparatus combines all the advantages of a man- 1 holerand flushtank and avoids all the incon veniencesottheflushtank now in use.

Having now described my invention, what Afdevice ofrthel character described, consisting ofi a chamber FfA, a vertical partition F near the center thereofan d dividingthe 45 chamber A into two portions, fM "and T, the portion T eont-ain ing the flushing mechanism? a? and? the faucet B, the portionM- containing the sewer E.con
